Logstash stuck

Elastic Stack Logstash
1

Guys need your help I'm desperate,
I'm trying to configure pipelines on logstash server , but it doesn't work , please take a look I'll be grateful to get some advice how to make it work
when I start logstash in the log file I get :

input conf file 01-beats-input.conf

input {
  beats {
    port => 5044
    client_inactivity_timeout => 600
    ssl => true
    ssl_certificate => "/etc/pki/logstash//il-infra-ls-ssa-stg1.crt"
    ssl_key => "/etc/pki/logstash//il-infra-ls-ssa-stg1.pkcs8.key"
    ssl_verify_mode => "peer"
    ssl_certificate_authorities => "/etc/pki/logstash//il-infra-ls-ssa-stg1.crt"
  }
}


output {
    if [log_type] == "secure"
     {
      pipeline { send_to => secure }
     }
    else if [log_type] == "syslog"
     {
      pipeline {send_to => syslog }
     }
}

syslog conf file :

input
{
  pipeline {address => syslog}
}

filter
 {
      mutate
      {
       replace => { "[@metadata][index]" => "syslog" }
      }

    grok
     {
      match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
      pattern_definitions => { "GREEDYMULTILINE" => "(.|\n)*" }
      remove_field => "message"
      }
    date
     {
      match => [ "syslog_timestamp", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
     }
 }

output
 {
   pipeline {send_to => elastic_out}
 }

and secure conf file 03-secure.conf:

input
{
pipeline {address => secure}
}


filter
 {
  mutate
    {
      replace => { "[@metadata][index]" => "secure" }

Any update on this please

4

why do you say it is not running? logfile says it is running

5

Yes its running but it stuck logstash doesnt receive any logs I suppresed all the pipeline accept the beat one and it doesn't write event into the file :

input {
  beats {
    port => 5044
    client_inactivity_timeout => 600
    ssl => true
    ssl_certificate => "/etc/pki/logstash//il-infra-ls-ssa-stg1.crt"
    ssl_key => "/etc/pki/logstash//il-infra-ls-ssa-stg1.pkcs8.key"
    ssl_verify_mode => "peer"
    ssl_certificate_authorities => "/etc/pki/logstash//il-infra-ls-ssa-stg1.crt"
  }
}


output {

    file
   {
    path => "/var/log/logstash/fallback.log"
    codec => rubydebug {metadata => "true"}
   }
#stdout { codec => rubydebug {metadata => "true"}}

#    if [log_type] == "secure"

#     {

#     }
#
#    else if [log_type] == "yum"
#     {
#      pipeline {send_to => yum }
#     }
#
#    else if [log_type] == "audit"
#     {
#      pipeline {send_to => audit }
#     }
#
#    else if [log_type] == "iis_log"
#     {
#      pipeline {send_to => iis }
#     }
#    else {
#          pipeline { send_to => fallback }
#        }

}
